[Bug middle-end/38250] ICE with -O2 -ftree-loop-distribution

In tree-loop-distribution.c (generate_memset_zero) can be DR_STEP(dr) NULL. But
it is passed into fold_build2 that expect two non null expressions. 

If program flow goes to end: due to goto then temporary variables created
during force_gimple_operand are added to referenced vars. But this variables
have not def bb. So later checks fails.
